I have sold these peanut pillows for comfort for 30 years in my office. But I finally found out how they work when I started to use one 4 years ago myself. I was miserable with radiating pain down my arm from a pinched nerve in my neck and had been for 4 weeks. A side sleeper, I could only sleep on my back for over a month on my regular support pillow. When I tried the peanut pillow, I could suddenly sleep in any position. It took 2 years to finally get the light tingling out of my forearm but the excruciating radiating full arm pain went away that first night. I will never go back to any other pillow, professional or casual, again. I have used these pillows for patients very successfully for similar problems for 4 years now. This pillow healed my cervical disc bulge. Easily and for a great price. 30 years of chiropractic care did not (I had mild symptoms for years that escalated over time). I assume that both were needed, but the real change came with the pillow. I am very grateful for your product!
